SPECIFICATION forming part of Letters Patent No. 592,279, dated October 26, 1897.

Application filed May 14,1897. Serial No. 686,541. (No model.)

To all whom it may concern:

Be it known that I, ORLANDO F. CONIHE, of Boston, (Oharlestown,) in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Valves; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to new and useful improvements in locking-valves for gas or other pipes.

My invention consists in certain novel features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of my device. Fig. 2 is a longitudinal section thereof with the valve' closed; Fig. 3, a similar view with the valve.

open; Fig. 4, a top plan view of the washergate, and Fig. 5 a plan view of the bottom of the body portion of my valve.

In the accompanying drawings the numeral 1 indicates the body of the valve,whichis provided with passages 2. and 3, having angle portions 4 and 5. the center of the body portion. 7 is held to rotate within this passage and is provided with a pin 8, extending therethrough. Recesses 9 are made at predetermined points in the body of the valve and are adapted to receive the pin 8 when the stem is turned to a certain definite position. A cap 10 is attached to the upper part of the body portion, preferably by a screw-joint, as shown. Within this cap is a spring 11, normally holding the pin 8 in contact with the body of the valve. The lower portion of the valve is provided with a valve-seat 12, and a recess extending approximately one-quarter way around the valve-seat is shown at 13. Upon this valveseat is fitted a washer-gate 14, provided with a passage 15, having a contracted end, as shown. Passages 16 extend from this passage around the valve and meet in an opening 17, which is adapted to communicate with the egress-pipe 3. A lug-18 is held within the recess 13 and regulates the extent of motion of the washer-gate. This washer-gate is further provided with a recess 19, in which is adapted to'fit a lug 20 upon the stem 7 When A passage 6 extends through A valve-stem said stem is forced in against the action of the spring 11. A cap 21' is attached to the lower portion of the body of the valve and .serves to hold the washer-gate in its proper position.

In operation the gas or otherfluid enters the valve by the pipe 2, passes downward when the valve is opened into the passage 15, thence around the stem by means of the passages 16 into the opening 17, and from there into the egress-passage 3. It will be observed from the drawings that owing to the peculiarly contracted shape of the passage 15 the admission of gas or other fluid can be controlled with extreme nicety. When it is desired to open the valve, the stem 7 is forced in against the action of the spring, thus raising the pin 8 out of the slots and forcing the projection 20 into the recess 19. By turning the handle of the stem the washer-gate will now be revolved, and as much as may be necessary of the passage 15 caused to pass below the angle portion 4 of the passage 2. The spring 11, by holding the pin 8 upon the upper portion of the body of the valve, will prevent the samefrom being turned without a considerable degree of force is exercised, and when the valve is shut off prevent it from being accidentally opened. This valve, by reason of the small opening that'is at first afforded, is especially adapted for use in pipes where the pressure is high and it is desired to gradually equalize the pressure on both sides of the valve.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a valve, a body portion having passages extending therethrough, a stem, a washer-gate carried by said stem and provided with a passage having a contracted end portion, passages extending around the open ing through which the stem passes and a recess communicating with said passages, and a cap extending from said washer-gate, substantially as described.

2. In a valve, a body portion havinga central passage adapted to receive a valve-stem, extended end portions provided with valveopenings, a stem held to rotate within said central opening, a washer-gate having passages therein adapted to be rotated by said stem, a cap held upon the body portion of said valve and adapted to retain the washer-gate in position, a cap extending over the upper portion of said stein having a recess therein, a spring held within said recess normally urging said stein outward, and a locking device adapted to hold said valve in closed position, substantially as described.

3. In a valve, a washer-gate having a central opening adapted to receive a valve-stein and provided with an entrance-passage havin g a contract-ed end, passages extending from said entrance-passage around each side of the central opening, and an egress-passage with which said side passage communicates, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
